The problem is that Tourism enables all that shit.

Also beyond that, it lets politicians get away with mismanaging a country because you don't need a highly qualified population with a good standard of living to sell the sights to foreigners.

The problem aren't the tourists individually, it's the systemic changes that their presence in large number innevitably leads to, especially in places were politicians are corrupt, refusing to take measures to at least stop the worst abuses and instead profiting from it themselves both directly and indirectly.
